TOILET APPLIANGE.

Application filed March 11, 1927. Serial No. 174,574.

the past has been the necessity of altering the closet structure to accommodate the attachment, rendering the bowl inconvenient when the supplementary seat is no longer required or when installed in transient institutions where the need is of short duration, and is not only an unnecessary but an unclesirable permanent fixture.

The attachments of this type susceptible of detachment have generally been insecurely fixed to the toilet causing a marring of the I finish on the seat that is both unsightly and unsafe. It has heretofore been impossible to effectively secure such a. seat to the same pivot upon which the main seat rotates, as when both the seats rotated around the same axis, the supplementary seat could not be positioned independently in a vertical plane.

There has also been lacking in previous devices any provision for extending or retracting the supplementary seat with respect to the main seat, or changing the point of rotation of the main seat to suit the particular requirements.

An object of this invention is to provide a supplementary toilet seat attachment which may be readily secured to any conventional toilet.

Another object of this invention is to provide a supplementary toilet seat which may be attached toany-conventional toilet without altering the structure, and readily detached.

Still another object of this invention is to provide asupplementary toilet seat which may be readily extended or retracted to suit particular requirements.

A further object of this invention is to provide a supplementary toilet seat attachment which maybe raised or lowered independent-1y of the main seat.

A still further object of this invention is to rovide a supplementary toilet seat at tac ment whiclli. will not mar the'finish en a toilet-i.

With these and other objects in view which may be incident to my improvements, the invention consists in the parts and combinations to be hereinafter set forth and claimed, with the understanding that the several necessary elements comprising my invention, may be varied in construction, proportions and arrangement, without departing from the spirit and scope of the appended claims.

In order to make my invention more clearly understood, I have shown in the accompanying drawings means for carrying the same into practical effect, without limiting the improvements in their useful applications to the particular constructions, which for the purpose of explanation, have been made thesubject of illustration.

In the drawings:

Figure 1 is a top plan vi-ewof the supplementary toilet seat attachment mounted on a conventional toilet;

Fig. 2 is an elevation sectional detail view showing the mounting and relative position of the main and supplementary seats;

Fig. 3 is a front sectional View of the clamp attachment taken on line 33 of Fig. 1.

Referring by numerals to the drawings wherein similar elements are designated by like symbols of reference throughout the several views and more particularly to Figure 2, there is shown a bowl 1 of any conventional type. The bowl 1 is provided with the usual rear extensions or shoulders 2. Passing through the extensions 2 and firmly secured thereto by any suitable means are'supporting standards 3. Interposed between the supporting standards 3 and the shoulder 2 are rubber washers 1.

Each of the standards 3 is formed with an integral annularly disposed reduced stub shaft portion adapted to be inserted in a hollow pivot bolt 5. A conventional seat 6 and a lid 7 are mounted for rotatable movement about the longitudinal axis of the pivot 5. The seat 6 is rotatably secured to the pivot 5' by brackets 8 and the lid 7 is similarly secured by a channel shaped bracket 9. The arms of the bracket 9 are extended downwardly from the lid and are apertured at their lower ends forming collars to afford a rotatable connection to the pivot 5.

The bracket 8 fixed to the bottom of the seat 6 is provided with extendin arms having a iertures ada ted to receivet e pivot 5 In tmanner t 9 seat 6 and the lid '7 piv shown otally mounted for rotatable movement about:

the longitudinal axis of the pivot 5. The foregoing description is that of a standard form of toilet seatnoW-in general use.

There is shown attached to the conven tional seat structure a supplementary;seat ll forming the subject matter of this invention, intended primarily. for the use of small children. The supplementary seat 11 adapted to be attached to any conventional seat structure w1thout the use of bolts, screws, on

any permanent-fastening means, comprises the seat 11 of any desired configuration-but preferably of a particular thickness forpurposes to be hereinafter more fully described. The seat 1s provided on the bottom with rub ber pads 12 which rest on the main seat 6 and serve to prevent-actual contact of the two.

"Secured to the rear portion of the supple- -;mentary seat is a flat plate-13 having apertures '14 adapted to receive screws 15. It is "preferred to mortise the bottom of the seat 12' to receive the plate 13 and. to countersink-- the screws 15 in the plate. VJhen thisform of construction'is employed the bottom of the seat 11 is flush with the supporting plate and .the assembled attachment maybe positioned in, greater proximity to the main seat 6.

The adjacentportion of the plate 13 is provided with a slot'16. 'The plate 13 is adapted 1 to slide in channel guides 17 formed integral with the sides of a clamp '18. The clamp 18 is provided with an'aperture 19 designed to receive a threaded bolt 20 adapted to engage a' slot 16- in the plate 13. The bolt 20 is adapt ed to receive a nut 21 to secure the plate 13 in any desired position within the limits of the slot 16. "The clamp 18 is also provided with an additional aperture 22' similar to; the aperture '19 adapted to serve a like, function, to allow greater adjustment of the plate 13. It is manifest that any number of apertures may be provided to increase the rangeof adjustabrasion that might be caused by the contactment.

' The clamp '18 is bent at 23as shown in Figure 2, to form a. semi-tubular porti0n'2 1 terminating in an upwardly extending flange 25;

The tubular portion, 24 is adapted to be held under its inherent resiliency to afford ready attachmentto' the pivot 5. The upturned flange 25 and the rounded surfacesat'the.

bent "point 23 affordunobstructed surfaces to facilitate attachment. To prevent any of the clamp 18 with the surfaceof the seat 6 it may be provided with a rubber washer .or any like guard, if so desired.

By the provision of the novel clamping attachment 18 the supplementary seat 11 as well as the lid 7 and the main seat 6 are adapted to rotate longitudinally about the axis'of the pivot5. -It will be noted from the construction of thehinge formed by the tubular sec tion-24 thatif the supplementaryseat is constructed of equal-or less thickness-than the .diameterof the pivot 5, that even though. the 11d 7 1s resting 111 a. vertical position, that the supplementary seat may be raised to a like position andpthe centeriofgravity will so fall that it will have no tendency to swing back. The; supplementary seat may be raised to inoperative position when the lid 7 is in any tposition-toathe left of a vertical plane, eliminating the disadvantages inhering in prior art devices of this general character, in which a supplementary seat 1 was mounted on thesame pivot which supported the main seat and lid. =1nsuch constructions it was necessary to move the lid somezdistance to the rear of the vertical plane in order tl'nrtthe supple- -mentary seatmight attain a position otrest,

same or less thickness as thediameter of the pivot, the lid 7 may be lowered to restfiatly on the supplementary seat withoutexerting any strain on the-bracket 9 or the'pivot 5.

The operation of this invention may be readily understood. The endof the-plate 13 projecting-from the rear ofthesup'pleinentary seat ll is fitted inthe channel guides formed integral with the-sides of the clamp 18 to any extent suitable for the particular requirements, and the-position of the plate on the clamp is fixed by the nut 21 within the limitation allowed by the slot 16.

It is manifest that the clamp 18 may be made in a single piece andattached directly I to the supplementary seat ll dispensing with the extension and retractionadjustment afforded 1n combmation with the plate 13, as

1 this is arefinement andnot abasic-feature of the invention. 1 The clamp 18 maybe readily attachedand firmly held on the pivot 5 by the spring tension of the tubular portion Qlland may be easily removedtherefrom.

This structure allows adjustment of the axis upon which the supplementaryseat r0 tates around-the'pivot 32 by changing the po sition of theplate 33 on the clamp 38. al lowingthe supplementary seat to be positionedto the left of the vertical when in nonoperative position. It is also'to be-.appreelated that the supplementary seatmay be extended or retracted in the channel guides 80 in thesame manner as the plate 13 may be adjusted in t-he elamp18yalthough if so desired the adjustment meehanismsmay be 'dispensedwith and-the plate 26 hinged directly to the plate 33 which-may be =fixed to the clamp 38, if so desired.

There is provided by this invention a supplementary seat structure that may be readily and firmly attached to any standard toilet seat Without altering the structure, that may be easily removed for cleansing. The seat may be raised or lowered independently of the main seat, and readily extended or retracted in position with respect to the main seat, to suit particular requirements.

IVhile I have shown and described the preferred embodin'ient of my invention, I wish it to be understood that I do not confine myself to the precise details of construction herein set forth, by way of illustration, as it is apparent that many changes and variations may be made therein, by those skilled in the art, withoutdeparting from the spirit of the invention, or exceeding the scope of the appended claims.
